15-Pin Apple/Mac II (VTG 150), MacII/Quadra (VTG 200)Output
All scan rate signals go to the VGA/
XGA (15-pin HD), Apple/MacII/
Quadra (15-pin) and BNC
connectors. The BNC output is individually buffered, allowing
devices to be connected to BNC and Apple/MacII/Quadra
outputs at the same time. However, because the VGA/XGA
and Apple/MacII/Quadra outputs are in parallel, they should
not be connected at the same time.

_ If devices are connected to both 15-pin outputs (VGA/XGA &

Apple/MacII/Quadra) simultaneously, the double termination

will result in a loss of brightness.

The pin assignments for the Apple/MacII/Quadra connector
are as follows:
Pin 1 = Red Ground Pin 9 = Blue
Pin 2 = Red Pin 11 = C/V Sync Ground
Pin 3 = Composite Sync Pin 12 = V. Sync
Pin 5 = Green Pin 13 = Blue Ground
Pin 6 = Green Ground Pin 14 = H. Ground
Pin 15 = H. Sync
9 Pin, TTL Output
A 9 pin “D” style connector provides all
TTL signal outputs. These outputs may
be selected from the TTL Scan Rates menu.
Pin 1 = Ground Pin 5 = Blue
Pin 2 = Red Intensity Pin 6 = Green Intensity
Pin 3 = Red Pin 7 = Blue Intensity
Pin 4 = Green Pin 8 = H. Sync
Pin 9 = V. Sync

_ When running TTL rates from outputs other than the 9-pin TTL

output, the test patterns may appear dim, distorted or

otherwise unlike the output from the 9 pin connector. This is

normal, due to the signal characteristics of TTL video signals.

Thus, for exact TTL signal duplication, only use the 9 pin TTL

output.

The VTG 200 (above)
provides six sets of
video output connectors;
the VTG 150 (at right)
provides four sets. Each
connector is marked for
its video application.
See the table of video scan formats on page 4-1 and choose
the one to be used to simulate your computer. Then connect
the appropriate cables to the device to be tested. (e.g.
projector, switcher, etc.)
15-Pin HD (VGA/XGA) Output
One connector is provided for the VGA/
XGA because the pin configurations are
identical. All scan rate signals go to the
VGA/XGA (15-pin HD), Apple/MacII/Quadra (15-pin) and BNC
connectors. The BNC output is individually buffered, allowing
devices to be connected to BNC and VGA/XGA outputs at the
same time. However, because the VGA/XGA and Apple/
MacII/Quadra outputs are in parallel, they should not be
connected at the same time.

_ If devices are connected to both 15-pin outputs VGA/XGA &

Apple/MacII/Quadra simultaneously, the double termination

will result in a loss of brightness.

The pin assignments for the 15-pin HD are as follows:
Pin 1 = Red Pin 8 = Blue Ground
Pin 2 = Green Pin 10 = Ground
Pin 3 = Blue Pin 13 = H. Sync
Pin 6 = Red Ground Pin 14 = V. Sync
Pin 7 = Green Ground
The sync available on pins 13 and 14 is dependent on the
position of the H/HV switch. With the switch in the HV (down)
position, composite sync is available on pin 13. With the
switch in the H (up) position, separate H and V sync is
available on pins 13 and 14.
